This is remarkable:
"researchers have found that in darkness most people eventually adjust to a 48-hour cycle: 36 hours of activity followed by 12 hours of sleep. The reasons are still unclear."

With alternative sleep cycles popularizing (i.e. biphasic, dymaxion, everyman), I wonder if we'll find that more efficient/healthy systems exist. It's very possible that our modern habits evolved in spite of best health, reacting to more immediate issues instead. But now, with a counter to the danger of darkness, we have an opportunity to experiment with otherwise-unrealistic cycles.
But then again, the 6-10 hour blocks we're acclimated to may be so deeply engrained that our health would face consequences in any other situation.
Are they really? I don't know of anyone who uses an alternate sleep cycle.
Small sample size, I admit...
